Crystallization and preliminary X-ray diffraction analysis of a lectin from Canavalia maritima seeds.

A lectin from Canavalia maritima seeds (ConM) was purified and submitted to crystallization experiments. The best crystals were obtained using the vapour- diffusion method at a constant temperature of 293 K and grew in 7 d. A complete structural data set was collected to 2.1 Å resolution using a synchrotron-radiation source. The ConM crystal belongs to the orthorhombic space group P2₁2₁2, with unit-cell parameters a = 67.15, b = 70.90, c = 97.37 Å. A molecular-replacement search found a solution with a correlation coefficient of 69.2% and an R factor of 42.5%. Crystallographic refinement is under way. [ABSTRACT FROM AUTHOR]
